A novel device for endoscopy-guided bladder catheterization outside of the operating theatre: early clinical experience.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
About 5-8% of bladder catheterizations are associated with difficulties. In such cases, the specialist is required to either perform suprapubic catheterization or catheter insertion under visual control in the operating theatre. Currently, a trial is assessing the efficacy, effectiveness and safety of Visus MG (a system for supervised safe bladder catheterization) in complex catheterizations after failed initial catheterization. To evaluate the rate of successful bladder catheterization, the complications rate and the ability to diagnose urethral pathologies with Visus MG in patients after failed primary catheterization, a prospective one-arm pilot study was initiated, including male patients with failed catheterization with a Foley catheter. A second catheterization was performed using the Visus MG (comprising a 20 Ch urethral catheter with an end hole at the tip, an optical part placed in a sheath, and an analogue to digital signal conversion unit connected to an image output device). The study evaluated the rate of successful catheterization, any complications that arose during catheterization, and the ability to diagnose urethral pathologies using Visus MG. 91 males were included. Catheterization was successful in 88 (96.7%) out of the 91 cases. In three cases (3.3%), the procedure was unsuccessful due to significant changes in the urethral mucosa following previous catheterization. There were no complications either during the Visus MG catheterization or in the immediate post-manipulation period. Bladder catheterization using Visus MG was successful in 96.7% of cases and showed no complications indicating that it is highly effective and safe to use in the event of previous unsuccessful catheterization, however, more prospective comparative trials are needed for relative effectiveness assessment. The advantages of this approach include portability, the ability to visualize the urethra, and the absence of any training requirements.
